85205310 ÷ 664 
We want to divide 85205310 by 664.

Moving on to step 1:
664 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 664

On to step 2:
664 goes into 85 0 times with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 664

Let's proceed to step 3:
If we divide 852 by 664, we get 1 and a remainder of 188.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 188 after subtracting 664 from 852.
Take the next digit (0) from the dividend and append it to 188, then repeat: 1880 / 664

Step 4:
When dividing 1880 by 664, we get 2 with a remainder of 552.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 552 after subtracting 1328 from 1880.
Include the next digit (5) from the dividend after 552, then repeat: 5525 / 664

Moving on to step 5:
664 can be fit into 5525 8 times, resulting in a remainder of 213.
Write down 8 as next digit of the result. 
Result so far: 128.0
Subtracting 5312 from 5525 leaves us with 213.
Append the next digit (3) from the dividend to 213 and continue with: 2133 / 664

Let's proceed to step 6:
664 goes into 2133 3 times with a remainder of 141.
The number 3 becomes the next digit in our result. 
Result so far: 1283.0
Deduct 1992 from 2133 and we're left with 141.
Append the next digit (1) from the dividend to 141 and continue with: 1411 / 664

Step 7:
1411 divided by 664 is 2 with a remainder of 83.
Use 2 as the next digit of our solution. 
Result so far: 12832.0
Deduct 1328 from 1411 and we're left with 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 664

Step 8:
When dividing 830 by 664, we get 1 with a remainder of 166.
The number 1 becomes the next digit in our result. 
Result so far: 128321.0
The remainder is 166 after subtracting 664 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 9:
The number 664 fits into 1660 2 times, leaving a remainder of 332.
Put 2 as the next digit of the answer. 
Result so far: 128321.2
Subtract 1328 from 1660 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 10:
If we divide 3320 by 664, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 128321.25
Deduct 3320 from 3320 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
0 divided by 664 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 128321.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 664 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 128321.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 128321.25, and the remainder is 0.0.
